LUBRICATING-CUP.

aerated To all may concern:

Be it known that I, LEIGH H. FISCHER, a citizen of the United States, residing at McCordsville, in the county of Hancock and State of Indiana, have invented certain new and useful Improvements in Lubricating- Cups, of which the following is a specification.

This invention relates to lubricators and especially to lubricating cups for crank pins, etc.

An object of this invention is to provide.

tion will be more readily understood from the following description takenin connection with the accompanying drawings and pointed out in the claim forming a part of this specification.

Referring to the a front elevational view of a lubricator constructed in accordance with my invention, a portion thereof being broken away to disclose details, and Fig. 2 is a longitudinal,

sectional view taken on the line 2-2 of Fig. 1.

In the drawings, the lubricating cup is generally designated at]. and comprises a transparent cylindrical body 2, one end of which is engaged in a base member 3, while the opposite end is engaged with a top or head 4:, as illustrated to advantage 1n Fig. 2. A

portion of the base 3 and top 4 are extended outwardly to provide an annulus equipped with knurled peripheries 5 in order to facilitate turning movement of the lubricating fhe base 3 is preferably made of metal, and has extending upwardly therefrom a tube 6, the latter extending through the head 4: and appreciably therebeyond. The upper end of said tube is closed and equipped with a central screw-threaded opening which alines with an opening 7 in the body of the base, the circumference of the latter mate- Specification of Letters Patent.

rially exceeding the circumference of the screw-threaded recess in the closed end of 'sa1d tube. The tube has openings 8 in its periphery in close proximity to its jointure with the body of the base. Aconical conducting nipple 9 is depended from the lower faceof the body, of said base 3, which issues 1nto a cylindrical collar 10, theterminal of the latter being constricted and provided on its outer periphery with screw-threads 11 to permit engagement of the cup with complemental screw-threads on the crank arm or the like. 7 i

Windows'or sights 12 are mounted in opposite sides of the members 9 and 10, whereby the contents of the latter will be readily discernible,

Concentrically mounted in the tube 6 is a screw-threaded rod 13, one end of which is equipped with a knurled head 14:, while the opposite end is bifurcated and the branches of the bifurcation flexed outwardly to provide fingers 15 for engagement with a spherical or ball'valve 16. A. valve seat 17 is mountedin the lower end of the collar 10 and is provided with a central opening, the wall of which tapers to receive the spherical valve 16, the valve seat being rigidly engaged with said collar and being normally engaged by the valve 16 when the cup is in an upright position.

In use therefore it will be seen that a liquid lubricantis to be used, and will feed by gravity through the openings 8 and into the chamber which is provided subjacent the body of the base 3 by the nipple 9 and collar 10 in conjunction with the valve 16 and valve seat 17. Communication is normally cut off through the valve seat 17 by said valve, the latter being unseated by movement of the crank arm or other element with which the lubricating cup might be associated, thereby permltting the lubricant to be dispensed through the central opening into the-valve seat and through the constricted end of the collar 10. Movement of the valve 16 will be limited in view of the screw-threaded rod 13, the fingers 15 of the latter lying in sufficiently close proximity to the valve 16 to permit a predetermined volume of the lubricant to be dispensed with each phase movement of the crank arm.

It will be understood .that the above description and accompanying drawings comprehendonly the general and preferred embodiment of my invention and that various mlnor changes 1n details of construction,

proportion and arrangement of parts may "when said receptacle is turned from an upright position, a screw-threaded rod adjustably mounted in said receptacle and having the lower terminals thereof bifurcated to embrace said valve for limiting the movement of the latter, and a housing for said rod extending through the receptacle.

In testimony whereof I aflix my signature in presence of two witnesses.
